I am trying to create a report with a drill down link to another custom report. It works fine in Visual Studio but when I try and run it in Vision I get the Object reference not set to an instance of an object error. Here is the xml from the rdl<Textbox Name="wbs1"> <Action> <Hyperlink>="http://Drillthrough/CRM Project Summary" &amp; "|WBS1|" &amp; Fields!base.Value &amp; "|FrameworkDrillTextBox|detail_WBS1"</Hyperlink> </Action> <Value>=Fields!wbs1.Value</Value> </Textbox>
